Glacial movements leave distinctive marks from "summary" of Principles of Geology, Volume 1 by Charles Lyell,Sir Charles Lyell
Glacial movements, as they advance and retreat, create distinctive marks on the landscape that can be observed and interpreted by geologists. These marks serve as a record of the past activity of glaciers, providing valuable insights into the history of the Earth's climate and geography. One of the most common types of marks left by glacial movements are striations, which are long, parallel grooves or scratches in the bedrock. These striations are caused by the abrasive action of rocks and debris carried by the glacier as it moves over the surface of the Earth. By studying the orientation and spacing of these striations, geologists can determine the direction in which the glacier was moving and the speed at which it was traveling. Another type of mark left by glacial movements is known as a moraine, which is a ridge or mound of unsorted sediment deposited by a glacier. Mor...
